My family's German so much of the meat prepared in that culture is veil (Schnitzel) or cabbage (sauerkraut) with sausage or pork hocks. I ate that at least once every couple of weeks when I was growing up. It was like having Eggs Benedict or apple pie for traditional American families. I don't know if vegans realize that a lot of when a lot of other cultures come to America they make their traditional recipes from whatever they can find. You can tell them to eat it with substitutes but they are still going to use whatever ingredients make it taste closest "to the way grandma made it." It's like... you can tell me that a non-alcoholic American beer approximates Weltenburger, but to me it's still going to taste like garbage.
